Remote desktopping between 2 computers on a LAN.

[Unconditional]

I have 2 computers in seperate rooms on a LAN, one of which can play television with a digital USB stick. What is the best way to remote desktop from the 2nd computer onto the first one so that I can use his TV program, and is it likely to be fast enough so that I can watch TV properly?

Can't plug the USb stick into another machine as I have no RF cord in this room.

I think its a 100mbs connection. Got it working and tried playing a video file over it but it was very choppy.
